International law is much debated and discussed, but poorly understood. Does international law matter, or do states regularly violate it with impunity? If international law is of no importance, then why do states devote so much energy to negotiating treaties and providing legal defenses for their actions? In turn, if international law does matter, why does it reflect the interests of powerful states, why does it change so often, and why are violations of international law usually not punished? In this book, Jack Goldsmith and Eric Posner argue that international law matters but that it is less powerful and less significant than public officials, legal experts, and the media believe. International law, they contend, is simply a product of states pursuing their interests on the international stage. It does not pull states towards compliance contrary to their interests, and the possibilities for what it can achieve are limited. It follows that many global problems are simply unsolvable. The book has important implications for debates about the role of international law in the foreign policy of the United States and other nations. The authors see international law as an instrument for advancing national policy, but one that is precarious and delicate, constantly changing in unpredictable ways based on non-legal changes in international politics. They believe that efforts to replace international politics with international law rest on unjustified optimism about international law's past accomplishments and present capacities.

Today international law is everywhere. Wars are fought and opposed in its name. It is invoked to claim rights and to challenge them, to indict or support political leaders, to distribute resources and to expand or limit the powers of domestic and international institutions. International law is part of the way political (and economic) power is used, critiqued, and sometimes limited. Despite its claim for neutrality and impartiality, it is implicit in what is just, as well as what is unjust in the world. To understand its operation requires shedding its ideological spell and examining it with a cold eye. Who are its winners, and who are its losers? How - if at all - can it be used to make a better or a less unjust world? In this collection of essays Professor Martti Koskenniemi, a well-known practitioner and a leading theorist and historian of international law, examines the recent debates on humanitarian intervention, collective security, protection of human rights and the 'fight against impunity' and reflects on the use of the professional techniques of international law to intervene politically. The essays both illustrate and expand his influential theory of the role of international law in international politics. The book is prefaced with an introduction by Professor Emmanuelle Jouannet (Sorbonne Law School), which locates the texts in the overall thought and work of Martti Koskenniemi.

This book addresses the themes of praxis and the role of international lawyers as intellectuals and political actors engaging with questions of justice for Third World peoples. The book brings together 12 contributions from a total of 15 scholars working in the TWAIL (Third World Approaches to International Law) network or tradition. It includes chapters from some of the pioneering Third World jurists who have led this field since the time of decolonization, as well as prominent emerging scholars in the field. Broadly, the TWAIL orientation understands praxis as the relationship between what we say as scholars and what we do – as the inextricability of theory from lived experience. Understood in this way, praxis is central to TWAIL, as TWAIL scholars strive to reconcile international law’s promise of justice with the proliferation of injustice in the world it purports to govern. Reconciliation occurs in the realm of praxis and TWAIL scholars engage in a variety of struggles, including those for greater self-awareness, disciplinary upheaval, and institutional resistance and transformation. The rich diversity of contributions in the book engage these themes and questions through the various prisms of international institutional engagement, world trade and investment law, critical comparative law, Palestine solidarity and decolonization, judicial education, revolutionary struggle against imperial sovereignty, Muslim Marxism, Third World intellectual traditions, Global South constitutionalism, and migration. This book was originally published as a special issue of Third World Quarterly.

Fifty years after the adoption of the Declaration on Permanent Sovereignty over Natural Resources by the General Assembly of the United Nations in December 1962, this volume assesses the evolution of the principle of permanent sovereignty over natural resources into a principle of customary international law as well as related developments. International environmental and human rights law leave unresolved questions regarding the limitations of this principle, e.g. extraterritorial and international influences such as the applicable criminal and tort law, as well as the extraterritorial and international promotion of good governance, including transparency obligations.
